You may be able to turn off some acceleration options in the video driver. Big bit block transfers from screen memory to main memory can bog the CPU down and cause latency hiccups. Or, it could be the network interface, which you can't change. If you have a hyperthreading CPU, you generally want to turn that off in the BIOS screen. Running glxgears puts up a 3-D display that mimics the load the Axis 3-D preview creates. Also, hide and bring back to foreground a couple windows on the screen. If those operations don't cause your latency bump, then it may be the network, you can try a few sftp file transfers to see if that is the cause.
